Stephan Kesting said:I really enjoyed this book. I have only one (small) reservation about it: it would have been nice if the authors could have identified the moves that require lots of flexibility, because I'm sure some young kid is going to crank his knee trying some of that stuff.
That being said there is still a ton of great material for people who aren't very flexible, and I highly recommend this book
